  • Product typeAC Adapters
  • Delivers 18 V 1 A power from 100-240 V AC input
  • Intelligent identification matches output to devices drawing 100 mA to 1000 mA
  • Eight interchangeable DC plugs cover 2.5 × 0.7 mm to 6.0 × 4.4 mm sizes
  • Center-positive polarity with 5.5 × 2.1 mm and 5.5 × 2.5 mm standard plugs included
  • Built-in over-voltage, over-current and short-circuit protection safeguards connected electronics

Universal 18V power adapter

This 18V 1A AC adapter delivers up to 18W with a positive centre pin. It ships with eight interchangeable DC plugs covering 4.0*1.7mm, 4.8*1.7mm, 5.5*1.7mm, 5.5*2.1mm, 5.5*2.5mm, 6.0*3.0mm, 6.0*4.4mm, 3.5*1.35mm, 2.5*0.7mm and an LED terminal connector. The unit accepts 100-240V 50-60Hz input and automatically matches lower current draws from 100mA to 1000mA.

Check device port and polarity

Verify that your equipment requires an 18V DC input with a centre-positive barrel jack. Confirm the plug outer and inner diameters match one of the supplied tips: 5.5*2.1mm, 5.5*2.5mm, 4.0*1.7mm, 4.8*1.7mm, 5.5*1.7mm, 6.0*3.0mm, 6.0*4.4mm, 3.5*1.35mm or 2.5*0.7mm. Ensure the device’s rated current does not exceed 1A and that the polarity symbol shows positive at the centre.

Replaces lost or proprietary 18V chargers

The adapter substitutes a missing or damaged 18V 1A supply for routers, audio gear, LED strips or small electronics that draw 100mA to 1000mA. The jump is worthwhile when the original brick is unavailable, when a single multi-tip unit reduces cable clutter, or when over-voltage, over-current and short-circuit protection are required for sensitive loads.

Questions about this item

What comes in the box with the BASEUS 18V 1A adapter and do I need any extra cables?

The package includes the 18V 1A power supply and eight interchangeable DC plugs covering sizes 5.5×2.1 mm, 5.5×2.5 mm, 4.0×1.7 mm, 4.8×1.7 mm, 5.5×1.7 mm, 6.0×3.0 mm, 6.0×4.4 mm, 3.5×1.35 mm, 2.5×0.7 mm plus an LED terminal connector; no extra cables are required.

How do I know which of the eight plugs fits my device?

Match the device's DC jack to one of the supplied plugs — 5.5×2.1 mm, 5.5×2.5 mm, 4.0×1.7 mm, 4.8×1.7 mm, 5.5×1.7 mm, 6.0×3.0 mm, 6.0×4.4 mm, 3.5×1.35 mm or 2.5×0.7 mm — and verify the device needs 18 V at 1 A or less with centre-positive polarity.

What does the 18 V 1 A rating mean when the adapter is powering my equipment?

It delivers up to 18 watts at a fixed 18 V, automatically supplying the exact current your device draws up to 1000 mA — whether that is 100 mA, 200 mA, 500 mA or the full 1 A — while built-in over-voltage, over-current and short-circuit protection keep the output stable.
